For those with a creak do you have a sunroof? I think there is more flex with sunroof cars as there is no strut in the roof connecting the b pillars. I think cars with no sunroof have his. My first golf had no sunroof and was tight. Current car with sr has more flex

Based on my current experience I am expecting some flex in my f30 when it arrives

I have tried to look for pics or vids or structure diagrams of the f30 frame with no roof to validate my assertion but no luck
